Fast-forwards are a way to update a branch with changes made on another branch. When pushing changes to a branch, Git will try to fast-forward the branch if possible, meaning it will apply the changes directly to the branch without creating a new commit.

The `git push --help` command provides more information on how to use fast-forwards, including how to force a non-fast-forward push if needed. It is important to understand how fast-forwards work to avoid accidentally overwriting changes made by other team members.

import requests from bs4 import BeautifulSoup def get_rental_info(url): response = requests(url) soup = BeautifulSoup(response.text, 'html.parser rental_list = soup_all('div', class_='content__list--item') for rental in rental_list: title = rental.find('p', class_='content__list--item--title').text.strip() price = rental.find('span', class_='content__list--item-price').text.strip() zone = rental.find('a', class_='content__list--item--des').text.strip() print(f'Title: {title}') print(f'Price: {price}') print(f'Zone: {zone}') print('---') page_count = 5 for page in range(1, page_count+1): url = f'https://sh.lianjia.com/zufang/pg{page}/' get_rental_info(url)

这段代码是一个简单的爬虫，用于从链家网上获取租房信息并打印出来。它使用了requests库发送HTTP请求，使用BeautifulSoup库解析HTML页面。

在函数get_rental_info中，它首先发送请求并获取页面的响应。然后使用BeautifulSoup将响应的文本解析为HTML对象。接着，它找到包含租房信息的div元素，并遍历每个租房信息。

对于每个租房信息，它找到标题、价格和区域，并打印出来。

最后，在主程序中，它设置了一个页面计数变量page_count，并使用循环迭代每一页的URL，并调用get_rental_info函数来获取并打印租房信息。

注意，这里的代码可能存在一些问题，比如缩进错误和变量未定义等。但是基本的逻辑和功能是清晰的。

请修改如下sql语句的语法错误：UPDATE sheet_sale_detail SET recent_price_avg = jsonb_set(recent_price_avg, '{0,avg1}', 7) where company_id = 99 and item_id =54209 and happen_time >='2023-07-01' and happen_time<='2023-07-11 23:59:00'

以下是已经修改的SQL语句：

UPDATE sheet_sale_detail
SET recent_price_avg = jsonb_set(recent_price_avg, '{0,avg1}', '7')
WHERE company_id = 99 AND item_id = 54209 AND happen_time >= '2023-07-01' AND happen_time <= '2023-07-11 23:59:00'

在原来的语句基础上，对于要插入的值7，使用引号将其包裹起来，以确保其被解析为字符串类型而不是数字类型。这样才符合jsonb_set函数的要求。同时，我还根据常规的SQL编码规范格式化了代码。
